Such configurations are often labor-intensive and error-prone, not only because of possible human error, but also because of the fact that the network layout of a wireless network often changes according to network expansion, or even because of environmental conditions

Embodiment Construction

[0022] The method and apparatus for routing messages based on physical layer information (such as physical layer identifiers) of the present invention can be used to support a communication session with one or more end nodes (such as mobile devices). The method and device of the present invention can be used with a wide range of communication systems. For example, the present invention can be used with systems that support mobile communication devices, such as notebook computers equipped with modems, PDAs, and various other devices that support wireless interfaces for device mobility.

[0023] figure 1 An exemplary communication system 100 implemented in accordance with the present invention, such as a cellular communication network, is described, which includes a plurality of nodes interconnected by communication links. The exemplary communication system 100 is, for example, a multiple access spread spectrum orthogonal frequency division multiplexing (OFDM) wireless communicati...

Abstract

Methods and apparatus for using end nodes, e.g., wireless terminals, to discover base stations and communicate information about discovered access nodes, e.g., base stations, to other access nodes in a system are described. As the wireless terminal roams in the system and new access nodes are encountered, one or more physically adjacent access nodes will be informed of the presence of the new access node as a result of communications with the wireless terminal. A message indicating an access node's inability to route a message to another access node which is known to a wireless terminal may trigger the wireless terminal to begin the process of updating access node routing and neighbor information.

Description

Technical field [0001] The present invention relates to a communication system, and more specifically, to a method and device for routing messages based on physical layer information in a wireless (e.g., cellular) communication network. Background technique [0002] The Open System Interconnection (OSI) reference model is useful in explaining various communication and routing operations. The OSI reference model includes 7 layers, where the application layer is the uppermost layer and the physical layer is the lowermost layer. The physical layer is a layer that deals with the actual physical connection in the system and the attributes of the physical connection. Above the physical layer is the data link layer, sometimes called the link layer. The link layer (layer 2 in the OSI model) is sometimes described as a technology-specific transport layer. Above the link layer is the network layer (OSI layer 3), which supports network routing and relaying. The network layer is sometimes ca...
